The short version

  • Only Proxmox Backup Server has a free tier, so it costs nothing to try first.
  • Each has a real cost: OwnBackup own states its products are officially part of Salesforce, and routes pricing to Salesforce's Cloud Data Security page rather than publishing a figure of its own; Proxmox Backup Server there is no Windows client, so physical Windows machines must be backed up by something else and the estate ends up with two backup products.
  • They diverge on capability: OwnBackup covers Automated backup, Proxmox Backup Server covers Deduplicated chunk store.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

OwnBackup

  • Own states its products are officially part of Salesforce, and routes pricing to Salesforce's Cloud Data Security page rather than publishing a figure of its own

Proxmox Backup Server

  • There is no Windows client, so physical Windows machines must be backed up by something else and the estate ends up with two backup products.
  • The datastore is millions of small chunk files, so it needs storage with real input and output capability and performs poorly on a single spinning disk or an SMB or NFS share.
  • Deduplication is per datastore, so splitting workloads across datastores for retention or tenancy reasons multiplies the storage those workloads consume.
  • Garbage collection depends on file access time semantics on the underlying filesystem, so a datastore mounted with the wrong options can fail to reclaim space or, worse, behave unpredictably.
  • Subscriptions are priced per CPU socket per year, so a backup server consolidated onto fewer larger dual socket machines pays twice per host for the supported repository.

Answered from the vendors’ own pages

OwnBackup: How do I get pricing information?

Pricing is available through a demo request. The homepage directs visitors to 'Get a Demo' to discuss specific costs. Ownbackup (now Own by Salesforce) provides Backup & Recover, Data Security, Data Mask & Seed, and Archive products.

Proxmox Backup Server: Can it back up machines that are not on Proxmox?

Linux hosts yes, through the client, at file level. Other hypervisors and physical Windows machines are outside its scope.

OwnBackup: Can I access pricing without talking to sales?

No. The pricing page exists at salesforce.com but the homepage directs all interested buyers through the 'Get a Demo' sales contact process.

Source
Proxmox Backup Server: Is a subscription required?

No. Without one you use the community repository and forum support. The subscription buys the tested enterprise repository and vendor tickets.

Proxmox Backup Server: How do I know a backup will restore?

Run verification jobs. They re-read the stored chunks and mark snapshots verified or failed, which is stronger evidence than a successful backup log.

Proxmox Backup Server: What storage should the datastore be on?

Local disks, ideally with ZFS and enough input and output capacity for many small files. Network shares are supported but routinely disappointing.
